Nasa has removed the asteroid Apophis from the risk list, says The Guardian.
In the year 2004 Concerns arose among Nasa scientists that the orbit of an asteroid named Apophis would coincide with Earth. Now Nasa says that this 340-meter-diameter asteroid will not hit Earth for at least a hundred years, says The Guardian.
In the past, concerns that the asteroid will pass the Earth alarmingly close in both 2029 and 2036 have already been shown to be futile. But there was still a fear that the asteroid could be on a collision course again in 2068. Now, even this threatening situation has been proven to be unfounded.
New telescopic studies justify Apophis has been officially removed from the asteroid risk list.
“According to our calculations, it will not pose a risk, at least for the next hundred years,” said Nasan Davide Farnocchia.
The next time the asteroid passes Earth from “near distance” on Friday, April 13, 2029. At that time, its orbit is expected to pass the earth at a distance of about 32,000 kilometers.
European The space organization Esa’s risk list includes 870 objects orbiting space near the earth. Previously, the 340-meter Apophis was in the top ten on the risk list.
A stone over a hundred meters could already destroy a big city. A kilometer-sized asteroid could cause global effects by plunging dust and ash into the air.
The asteroid that destroyed the dinosaurs and much of the rest of life was about ten miles in size.
Of the risks to the Earth, an asteroid collision is the least likely to reach. And if a space rock collided with the Earth, it would most likely hit the sea or a desert area.
